why are data rates so low on "larger" bandwidth links

[Wizumwalt]

I've got an 802.11n access point that, and as the vendor says, does 600Mb/s.

I have two laptops w/ gigabit nics on each end. When I run IPerf accross this wireless link, it transfers 38MBytes in 10 seconds and the result is 31Mbit/s.

I don't understand this? That's only 3.87MB/s, correct? How is this calculated and why is it only that much? I've even seen other 802.11n manufactures that claim less around 150Mps, but 31Mbit/s?
